CHARLES BRADWAY, or MAQUOKETA, IoWA.

Letters Patent No. 92,787, dated July 2(1), '1869.

To all whom it may concern Be it known that I, CHARLES BRADWAY, ofMaqncketa, Jackson county, State of Iowa, have invented new and usefulImprovements in Bed-Springs; and I do hereby declare the following to bean exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked t1lereon, making a partof this specification, in which- Figure l represents a top View, and

Figure 2, a side view of the hed-spring.

Figure 3, the notched slat.

Figure 4 represents a view of the side and crossslats withy their sideand centre springs.

The nature of my invention consists in the passing of the inverted stemsof' the spiral springs through holes in the side-rails of a bedstead,and forming the lower ends of the stems into stirrups, for the receptionof the ends of th cross-rails, that are the main-body springs, andarenotched at the ends, so as to be held permanently by the stirrups.

A represents the side-rail, with a round aperture, B, for the stem O ofthe spiral spring D to play in loosely.

The one end ofthe spiral spring is attached perma-l nently to theside-rail A, by being driven into the rail, and held to its place on thetop of the rail by a clip, E.

The spiral spring D is formed of one wire, having an inverted stemextending from the top of the conical spiral through the centre, passingthrough the aperture B, and bent in a square stin'up, F, underneath theside-rail, and in which the main-body spring or crossslat G fits firmlyand tightly. This lower body-slab G `is notched at its end in an angularnotch, wider at the outer end, something similar to a half dovetail, andthe stirrupF ts tightly around the narrow side of the notch H, and restsagainst the shoulder of the notch, braces, clasps, and holds the end ofslat G firmly and permanently, to prevent any lateral movement, whilstit yields with the spiral spring in an easy np-aud-down motion, making abed much more elastic to rest upon, and also not so liable to break orinjiu'e the spiral spring by a sudden or heavy pressure. f

The slats G extend across the bedstead at rightangles with theside-rails A, giving to the bedstead an even and regular spling, andalways keeping a level posi- 'tion without any sagging.

The centre spiral springs J are connected springs, commonly used onbedsteds, and are attached to the cross-slats G, (between the side-railsA,) and` upon which the bed. rests with an even and regular pressnre.

' lVhat I claim as my invention, and desirev to secure by LettersPatent, is-

1. 'lhe cross-slats G, in combination with the sidebars D, thesuspemling-springs C, and the intermediate springs J.

' 2. suspending the cross-slats G, by their notched ends H, to thestirrup ends F of the spiral-spring stem C, as herein described, and forthe pulpose set forth.
